Weed stocks were sliding from their post-election peaks Thursday as worries surfaced that the successor to former Attorney General Jeff Sessions could also be against legal marijuana.

Pot stocks rallied on Wednesday, with Tilray surging more than 30%, after Michigan became the 10th US state to legalize marijuana and as Jeff Sessions, a long-term opponent of legal weed, resigned as the US's attorney general. In January, Sessions rescinded an Obama-era policy directing states to make their own decisions on cannabis without federal.

While Sessions' resignation has brought optimism for legal-marijuana advocates, Trump is reportedly considering other opponents to replace him.

"There is a risk that Trump will nominate a new Attorney General who is anti-cannabis," Cowen analyst Jaret Seiberg wrote in a note. "It is why we continue to see legislation as the path forward for medical use, veteran access, and banking services."

CBS reported that the president is considering former New Jersey Gov. Chris Christie, who is also opposed to legalizing marijuana, to fill the position.

The Wall Street Journal says that Health and Human Services Secretary Alex Azar, outgoing Florida Attorney General Pam Bondi, and Trump lawyer Rudy Giuliani are also on the list.
